when depressing the clutch to shift, the heat shield rattles . The one ontop of the Cat Conv. I'm planning on cutting it off with a pair of metal shears. This will avoid any rusted hardware and removing the Cat. Conv. I've already cut some rusted pieces from the top where water builds up.

The heat shield appears to be connected with 2 bolts that run throuth the floor board. This would require alot of interior dismanteling.
